Gyrrian Del'Kor was a Givin astrogator that served the Confederacy of Independent Systems' Theoretical Astrogation Division. Before the Separatist Crisis he was a member of the Body Calculus, the governing body of Yag'Dhul. As a gifted mathematician, he used his talents to suggest troop and fleet positions for the Confederacy during the Clone Wars. He was a welcome guest and commentator on the CIS Shadowfeed to provide his analysis on current events in the war. Gyrrian introduced and supervised the Spine Lock, a defense measure in which the Confederacy placed asteroid bodies on various positions along the Corellian Trade Spine, in order to secure and protect Confederate holdings that had recently been conquered during Operation Durge's Lance. The success of this measure awarded him the Order of Dooku.
